Title:

Thermopower of Co-doped FeSe0.82

Abstract:

The effect of cobalt doping (0.05 ≤ x ≤ 0.50) on the thermopower of the newly discovered superconductor FeSe0.82 is investigated through electrical and thermal transport measurements. Our results point to the destruction of superconductivity at very low Co concentrations. Thermopower data suggest negative charge carriers along with a large enhancement of the Seebeck coefficient S on the order of ≈ -80 uV/K around T = 100 K.
